The published API lives in subversion/include, where all functions
have single underscores. These are highly impacted by our versioning
requirements.

"Semi-public" (which is a term I too use) would be stuff in .h files
scattered amongst the library subdirs themselves
(clients/cmdline/cl.h, libsvn_wc/wc.h, etc.). These functions have
double underscores and are not impacted by our versioning
requirements.

Finally, I used "private" to mean those functions that don't live in
any .h files, are marked "static", and are visible only to the other
functions in their particular .c file.
